Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967144, here are decompositions:
- 163 + 4294966981 = 4294967144
- 331 + 4294966813 = 4294967144
- 487 + 4294966657 = 4294967144
- 907 + 4294966237 = 4294967144
- 967 + 4294966177 = 4294967144
- 991 + 4294966153 = 4294967144
- 1297 + 4294965847 = 4294967144
- 1303 + 4294965841 = 4294967144
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 255.255.255.104.
